I feel bad for her, but this makes sense. They obviously always had the second album planned for 2016, that's why the tour was supposed to be Q2 to Q4 2015, then prepare for the new era. With the postponing tour, the tour conflicted all of their album plans, which are much more important than a tour that wasn't selling that well (I think?)
She needs to keep her relevance and deliver more hits and then she can tour the next era. I wish her good luck, she doesn't seem like a bad girl
